T all whom it nwyvoneem:

Be it known that we, FREDERICK GEORGE Sommrrz and WILLIAM: H. HARMAN,citize'ns of the United States, and=residents o f Phila- 5 delphia,Pennsylvania; have invented C61- tain new and usefnl Improvments inClothes Wringers, of which the following is a specificatio Our inventionrelates to clothes-wringers, more particularly those having frames madeof met al, and one object of our invention is to prdvide aclothes-wringer with quickaciping release mechanism fortlxepressureapplying means for the squeeze-rolls'.

A further object of our invention is to provi de a clothes-wringer'having a frame made wholly of me tal with quick-acting relea.semechanism 'for the pressure-applying means for the squeeze-r0lls,disp0sedadja- 29 cent one end of the upper squeeze roll; the

opposite end of said. roll being'automatically released in a mannerhereinafter described.

A further object of our inventi'on is to provide such qu'ick-actingrelease mechanisn'1 adjacent the gearing for' the squeeze-rolls, and astill furtl1er object of our invention is to provide simple and efllcient device for actuating the quick-release means and for ohis purpose weprefembly employ a knock-ofi 39 device connected to one of the tensionbolts formi part of the mechanism,which retains t e squeez8-rolls inplace and appliea the desired pressure thereto; These and otherfea.tures of our invention are more fully described hereinafter,reference being had to the accompanying drawings, in which:

Figure 1, is a frontgelevaliion of one form of clothes-wringer to whichour improve'd quick-release device may be applied.

Fig. 2, is an end elevation look'mg in the direction of the arrow, Fig.1.

. Fig. 3, is a diagrammatic view illustrating the osition of' thesqueeze rolls after the operation of the quick-release device for thepressure-applying means therefor, und. Fig. 4 is a fragmentary viewillustrating certain details o-f construction, in section on the lineIVIV Fig. 1. 1 The wringer frame 150 which the features constituting ourpresen't inven n have been 'applied may be of' metal, bstantially U-shape in contour, and maycomprise upright 9nd portimis with g lgw9!COI1necting cross pne 0x a plunality of sections.

mgs we have illstrated a wringer 'frama .made of a plurality ofsections, 1 und 2, fitbar therefor; such fmmle bei formell in n thedrawting togqther 01'1 a median o r substantia-lly med1an l 1ne, asclear illustrated in Fig'. 2;

und secured t0gether y suitable means, such for instance as rivets 3.While the use of our invention 'is not limited theretoit is .shown inconnectio n With a Wringer frame of thetype illstrateel and described inthe pending applicat ion f F. G. Schranz, filed February 19, 1921,Serial N0. 446,226. The sections 1 and 2 0f the frame am vided withupright end portions 1* an 1", and 2 and 2", und these end portions maybe Provided with inwardly disposed flanges or ribs 4, providing channelsadapted to receive bearin blocks 5, fo r the spindles 6, of

squeeze rol s 7 und said bearing blocks.

may havia side ribs fitting the channels provided by the inner flangesofsaid end. portions. These bearings am -preferably cf hard wood, andmay be cut from a pre-. viously formdd blank in the manner describe'd inthe applicatio1h of F. G. Schranz, filed Sept. 24, 1920, Serial Nurnber412,449. The bearing blocks 5 are applied to the upper side ofthespind-le of the pper roll and to the lower side of the spindle of thelow.er roll, and the lower bearing blocks may be supported by inwardlydisposed lateral pro jeclsions carried by the upr1ght end portwns of theframe.

At one side of tlie wringerframe a housin .9 is Provided, which may beintegral w;th the upright end portion of the frame, and this housmgreceives the gears 10 and 11 carried by the spind-les 6 of the sque9zerqlls 7 Wheh the frame is 1 ixade in a plurality 0f sections, suchhousing may v be formed one half on each upright encl p1"- tion 1" and2" of the sections making up the frame.

Hinged at12 to the upright end portions 1. and l", of the section 1,are=cap members 13 und 14, Which overlie the top of these end drawmgs;and these cap m@mbars carry at their opposite enrls bolts 15 und16,-hung ortions, as clearly illusttated in tlm from pivot ins 15,and-16, mounbed in pairs of ears 13 und 14 of the res ctive cap members;said bolts being adapte to undenupright end portions 2 and 2 of thesecti on 2. The bolts 15 and 16 carry springs 19 mterposed betweenwashers 20 and.20 also carried by the bolts and which may be lying meansfor the squeeze-rolls 7 mcludes lugs or projections 22 disposed on theunder sides 0f the cap'members 13 and 14, and preferably integraltherewith; such lugs or'projections directly engaging Wear pieces 24, inehe form of metal yokes, carried by the bearing blocks 5, for ehespindle of the upper squeeze-roll.

In this arrangement of quiek-release mechanism for the squeeze-rolls,which mechanism is located at one side only of the wringer frame, theholt 16 is provided With an upwaxdly extending member 25, terminating ina band plate 26, which extends over the squeeze rolls. The member 25 maybe integral with the holt 1601 rigidly secured thereto. Depression ofthe band p-laoe 26 or movement in t-he direction of the arrow w, willswing the bolt 16 on its pivot pin 16, and release its spring 19 fromengagement with the pairs of lugs 18 ofthe upright end portion; therebyrelieving the pressure applied by said spring at one end of thesqueeze-rolls. T0 com'pletely release this pressure-applying device itis only necessary to depress the handle 25 to the position shown bydotted lines in Fig. 2, whereupon the spring holt 16 and the cap member14 will be withdrawn from their operative engagement with the lugs 18.and the upper roll Will be completely freed from the pressure applied bythe springe 19.

In this arrangement of quick-release device, only one end 0f t-he uppersqueeze roll is relieved, -As the opposite end of said upper roll isunsupported, however, the bearing block therefor being disposed abovethe spindle to take th e upward thrust, said upper roll is free t0 drop.at its unsnpported end and may rise at the end normally umlerlying capmember 14, when the latter has been rernoved as above described and asclearly indicated in the diagrammatic view, Fig. 3, comnletely removingall danger of injury to the operator should a finger or other portion ofthe band be caught between the rolls; er to the wringer frame. should'the matarial passed between the roll s tend to pile up. Should the uppersqueeze roll continue to turn after the p-ressure at one end of the Sameha.s been released in the manner indicated, it will draw away from theframe and be wholly free as indicated by its position in dotted lines,Fig. 3.

As in" the pending application Serial Number 412,449, before referredto, a drain board 30, also of metal may be arranged to lie belowhousings 31, formed on the 1nside of the upright end p0rt-ions of theframe for the outer ends 0f the squeeze rolls, andthis drain lioard maybe 'adjustably held in place in the same manner as illustrated in saidapplication. The usual guide plates 32 to d1rect the garments to thebite of the squeeze rolls may be employed. as in all similar structures;said guide plates having projections 33 Which engage the edges of thehousin s 31.

ower to drive the squeeze rolls may be applied to either spindle but inthe present case we have shown the lower spindle as projecting beyondthe end of the frame, as i ndicated at 6?, for operative engagement witha driving element; the shaft of' a suitably aet-uated motor forinstance. In lieu of this, the projecting spindle may be engaged by asuitable crank-handle, 01' o ther form of power-applying member..

As in the structure of the pending application Serial Nu1nber 446,226before referred to, it will be readily understood that if both capmembers- 13 and 14 are released from' their spring efigagernent with theframe and swung back an their hinged counection with the upright endportions there- 0f, the squeeze-rolls .7, with the bearingblocks 5, maybe removed. This peirmits ready assembly and removal of the variousparts 0f the structure, for renewing J;he bearings 01' squeeze-rolle; erother repairs, as occasion may require. There are n0 parts to geb out oforder 'or readily break, and any suitable form of clamping device may beemployed to att-aeh 0111 improved wringar to a. washing machine or tub,er at any other diasired point.

It will be understood that we do not wish t0 be limited to the' exactronstruction disclosed in the drawings and deseri bed herein, and ourclaims are designed t0 cover any equivalent construction having thestune 0r a similar object in vieW. lt will also be understood that ourimprovements may be applied to wooden or metal frames, and that thelatter may be made of cast er pressed metal, withbut departing from ourinvention.
